Computers often encounter various problems, among which power failure is a common problem. Power failure will affect the normal startup and operation of the computer, and may even cause hardware damage. PHP editor Youzi brings you a computer power failure troubleshooting and repair guide. Starting from the common manifestations of power failure, it analyzes the cause of the failure step by step and provides detailed repair methods to help you solve the problem of computer power failure.
Computers are essential equipment in modern life and work, and power supply problems are one of the common computer failures. A computer power failure may prevent the computer from booting or even further damage other hardware components. This guide will help you understand the common causes of computer power failure and provide corresponding repair methods.
Causes of computer power failure may include power line failure, power supply problems, power switch failure, etc. Among them, power line failure may be caused by damaged wires or poor plug contact. Power supply problems may be caused by overloading or aging of the power supply. A faulty power switch may be caused by long-term use.
When the computer has booting problems, you first need to check whether the power line is well connected and confirm that the power plug and connections are not loose or damaged. If there is no problem with the power line, you may need to further check the power supply and switch conditions.
When troubleshooting a power failure, you can first try to use other proven and reliable power lines to connect to confirm whether there is a problem with the power line itself. If the problem persists after replacing the power cord, it is likely that the power supply is faulty. At this time, it is recommended to seek professional help. After all, the internal structure of the power supply is relatively complex and requires professional knowledge and equipment for repair.
If there is no problem with the power supply, the power switch may be faulty. At this time, the power switch can be disassembled and inspected to confirm whether there are any damaged or aging parts. Failures of the power switch also need to be repaired with caution and ensure that the operation is carried out under the guidance of professionals.
When performing power supply maintenance, be sure to pay attention to safety, especially when it comes to the power supply part. Make sure to operate in a power-off state and avoid touching high-voltage components to avoid accidental injury.
At the same time, if you do not have relevant maintenance experience and professional knowledge, it is best not to try to disassemble components such as the power supply to avoid more serious failures or safety hazards. It’s also wise to seek professional repair services or consultation.
Thank you for reading this computer power supply troubleshooting and repair guide. I hope it can help you better understand and solve computer power supply failure problems.
Computer power supply is a very important component of the computer system. It is responsible for providing a stable power supply to the entire computer system. But the power supply is also one of the most failure-prone components of a computer. When the power supply fails, it will seriously affect the normal operation of the computer. Therefore, it is very necessary to detect and troubleshoot power failures in time.
Power failure usually manifests itself in the following situations:
The power supply cannot be turned on: After pressing the power button, the computer screen, fans and other equipment cannot start, indicating that the power supply may have a serious failure. The power supply frequently shuts down automatically: During use, the computer will suddenly lose power or restart automatically. This is usually caused by unstable power output. The power supply makes abnormal sounds: The power supply makes abnormal buzzing or hissing sounds when working. There may be a problem with the internal components of the power supply. The power indicator light is abnormal: The power indicator light does not light up or keeps flashing, which may also indicate a power failure. Computer performance decreases: The computer runs slowly, and occasionally a blue screen or program crashes. This may be caused by insufficient power output from the power supply.When we find that the computer has the above faults, we need to carefully check and diagnose the power supply to find out the root cause of the fault. The specific diagnostic steps are as follows:
Check the power cord: First, check whether the power cord is in good contact and whether the cable is damaged. Observe the power indicator light: Check the status of the power indicator light to see if it lights up normally. Measure the power supply output: Use a multimeter to measure the output voltage of the power supply to see if it is within the normal range. Check the power supply fan: Observe whether the power supply fan can operate normally and cannot hinder the heat dissipation of the power supply. Replace the backup power supply: If no problem is found in the above steps, you can try to replace the backup power supply for testing.Based on the diagnosis results, we can take the following repair measures:
Replace the power cord: If the power cord is damaged, it needs to be replaced in time. Clean the inside of the power supply: Use compressed air to clean the dust inside the power supply to improve the heat dissipation effect. Replace the power supply fan: If the power supply fan fails, you need to replace it with a new one. Replace the power module: If the power supply still does not work properly after the above inspections and repairs, the entire power module needs to be replaced.Repair of power failure requires certain professional knowledge and operating skills. If you don’t know much about computer repair, it is recommended that you find professional maintenance personnel to check and repair it to avoid causing greater damage.
Through the above content, I believe you have a deeper understanding of computer power failure. If you encounter any power-related problems while using your computer, please feel free to contact us. We will do our best to provide you with professional and thoughtful service. Thank you for reading and I wish you a happy use!
There are many, the common ones are no response when turning on, blue screen of death, automatic shutdown, unstable power supply, etc. These faults may be caused by poor contact of the power line, serious dust accumulation on the power supply fan, insufficient power supply, adapter failure, etc. If the above fault occurs, it is recommended to first check whether the power line is in good contact, clean the dust on the power fan, replace or repair the adapter, etc. At the same time, paying attention to keeping the computer cool and not operating it excessively can also effectively prevent the occurrence of power failure.
The computer power supply is broken. The power supply has no output. When the power supply is under load and the DC voltage at each output terminal cannot be measured, it is considered that the power supply has no output. At this time, you should first turn on the power supply and check the fuse, and analyze the fault scope through the blown fuse.
1. If the fuse is blown and turns black, it means there is a serious short circuit. You should focus on checking the rectifier, filter and power inverter circuit.
(1) The AC filter capacitors C3 and C4 are short-circuited due to AC surge voltage breakdown. Some ATX power supply AC filter circuits are more complicated, so you should check whether there are short-circuited components.
(2) A diode in the bridge rectifier circuit of the main communication circuit breaks down. Cause of damage: Because the DC filter capacitors C5 and C6 are generally large-capacity electrolytic capacitors of 330μF or 470μF, the instantaneous charging current can reach more than 20 amps. Therefore, an instantaneous large-capacity surge current can easily cause a rectifier tube in the rectifier bridge with slightly poor performance to burn out. In addition, the AC surge voltage will also breakdown the rectifier diode and cause a short circuit.
(3) The DC filter capacitors C5 and C6 in the rectifier and filter circuit break down or even burst. Cause of damage: Because the withstand voltage of large-capacity electrolytic capacitors is generally about 200V, but the actual working voltage reaches about 150V, which is close to the rated value. Therefore, when the input voltage fluctuates or some electrolytic capacitors are of poor quality, breakdown capacitance may easily occur. In addition, when the electrolytic capacitor leaks, it will become severely heated and burst.
(4) The commutation diodes VD1 and VD2 and the power switching transistors VT1 and VT2 in the DC conversion circuit are broken down and damaged. Reason: Because the output voltage after rectification and filtering is generally around 300 volts, and the load of the inverter power switch tube is a rational load, the voltage peak formed by the leakage inductance may be around 600 volts, while the withstand voltage Vceo of VT1 and VT2 is only 450 volts. Fu left and right. Therefore, when the input voltage is high, some switching tubes with low voltage resistance will be broken down. Therefore, you can choose a power switch tube with higher voltage resistance.
2. The fuse is blown but does not turn black, indicating that it is not a short circuit that caused the fuse to blow.
(1) The fuse will blow out the moment the power is turned on, mostly due to the instantaneous large current that will blow out the fuse, such as the charging current of the DC filter capacitor when starting up.
(2) If the fuse is blown during use, it is mostly caused by excessive load.
3. The fuse is not blown, such as the power supply has no output. If the fuse is intact, you should check whether there is an open circuit or short circuit in the power control circuit, whether the overvoltage and overcurrent protection circuit operates, and whether the auxiliary power supply is intact, etc.
(1) The current limiting resistor THR of the communication input circuit is open circuit, and the 300V DC voltage cannot be measured at this moment. The switching power supply uses a 220V direct rectifier filter circuit. When the AC voltage is connected, there will be a large surge current (capacitor charging current). The surge current can easily cause the current-limiting resistor or the fuse to blow.
(2) The auxiliary power supply does not have +5V voltage output. You should focus on checking the relevant components in the auxiliary power circuit, such as the VT15 vibrating tube of the auxiliary power circuit is damaged, the VZ16 voltage regulator tube, VD30, VD41 diodes are broken down and short-circuited, and the current limiting resistor R72 may be faulty. 5. How to detect computer power supply failure?
1: Prepare a wire, any kind of wire will do.
2: Remove the power supply from the computer, take the wire and insert it into the green wire interface of the 24P plug on the power supply.
3: The other end can be plugged into the socket of any black wire on the 24P head of the power supply. After plugging it in, connect the power cord to the row of seats.
4: After connecting both ends of the lead-in cable, check whether the power supply fan is spinning. If it turns normally, you can be sure that the power supply is good.
Reminder: The 5V current of the small wire on the 24P connector on the power supply is not harmful to the human body, so don’t be afraid.
If your Great Wall computer encounters a power failure, you can try the following troubleshooting steps:
1. Check the power cord: Make sure the power cord is intact and properly connected to the computer and wall outlet. If the power cord is damaged in any way, try a new one.
2. Check the power plug: Make sure the power plug is tight and correctly inserted into the computer's power jack.
3. Power Outlets and Power Strips: If using a power strip, make sure the power strip is working properly and connected to a working power outlet. Try plugging your computer directly into a wall outlet to troubleshoot the power strip.
4. Restart the computer: Sometimes the power management inside the computer can cause problems. Try shutting down the computer completely, waiting a few minutes and then restarting.
5. Disconnect external devices: Disconnect all external devices (such as printers, extended hard drives, USB devices) from the computer, and then restart the computer to see if the problem can be solved. Sometimes a fault in an external device may interfere with the computer's power supply.
6. Power supply unit (PSU) failure: If the above steps do not solve the problem, the power supply unit may be faulty. At this time, it is recommended to contact the after-sales service center of Great Wall Computer, or ask a professional technician to check and replace the power supply unit.
Please remember, do not attempt to repair the power supply unit or other computer hardware parts yourself, as this may cause further damage or safety issues. Computer hardware failures are best handled by professionals.
Whether it is for business office or daily entertainment, laptops are an indispensable and important tool in modern life. However, power failure is one of the most common problems of laptop computers, causing a lot of inconvenience to users. This article will provide you with a comprehensive notebook power supply repair guide to help you easily solve power-related problems.
Before repair, we first need to understand some common power failures and their possible causes: The battery cannot be charged: It may be caused by battery aging, charging line failure or damage to the power adapter. Short battery life: Usually caused by too many battery cycles or improper system settings. No output from the power adapter: It may be caused by damage to internal components or oxidation of the interface. The notebook cannot be turned on: it may be caused by the battery being completely exhausted or the motherboard circuit failure.
Depending on the type of fault, we can take the following maintenance methods: Replace the battery: If the battery cannot be charged normally or the battery life is significantly shortened, it needs to be replaced with a new battery. Clean the interface: If the power adapter has no output, you can try cleaning the interface with an alcohol cotton ball to remove oxides. Replace the power adapter: If the problem still cannot be solved after cleaning the interface, you need to replace the power adapter with a new one. Check the motherboard circuit: If the notebook cannot be turned on, you may need to check whether the motherboard circuit is faulty.
In order to extend the service life of the laptop, we also need to pay attention to the following points: Maintain good heat dissipation and avoid long-term high-load operation. Clean the fan and cooling holes regularly to keep ventilation smooth. Do not completely discharge the battery for a long time and keep the battery between 20% and 80%. Avoid falling or severe vibration to avoid damaging internal components.
Thank you for reading this laptop power supply repair guide. Through this article, you will be able to better understand common power failures and their causes, and master some basic repair methods. At the same time, we also shared some preventive maintenance tips, hoping to help you extend the service life of your laptop. If you have any other questions or need professional assistance, please feel free to consult.
1. The computer cannot be turned on or shuts down immediately after being turned on. This is a common symptom of power failure. 2. If the computer beeps or beeps briefly when starting up, it may be caused by a power failure. 3. The computer suddenly freezes or various strange error prompts appear, which are also possible manifestations of power failure. Explain the reason: Power failure may be caused by aging, poor quality or overload of the power supply, which will affect the normal use of the computer. If these problems occur with the power supply, it must be replaced or repaired in time. Content extension: Although power supply failures are relatively common, not all power supply problems require replacement of the power supply. Sometimes it is just necessary to perform the correct treatment to repair the fault. However, in order to avoid losses caused by power failure, it is recommended to check the computer hardware regularly, paying special attention to the working status of the power supply.
If the power switch of the desktop computer does not provide power, first, check the power supply and power plug. Some computer power supplies have switches. Check if it is not turned on. If the computer power supply is damaged, or there is a problem with the computer motherboard, you can open the computer case. Short-circuit the green wire and the black wire on the plug of the power supply to the motherboard and see if the power fan rotates. If it rotates, it means there is a problem with the computer and the power switch. If it does not, it means there is a problem with the computer's power supply.
Sit comfortably in your favorite computer chair, snap the monitor switch on, and press the power switch. You're greeted by the reassuring rattle of your computer and the whir of a cooling fan. You lay back slightly against the back of the chair and watched absentmindedly as your old friend started to get started.
The question you have asked yourself hundreds of times comes to mind again: why is the computer starting up so slowly these days? Then the unfortunate happened. The hard drive sputtered endlessly, eventually turning into a loud, heart-wrenching noise. Flashing across the screen was "Failure Fixed Disk 0", or something similarly ominous. You feel a sinking feeling in your stomach—the hard drive is in trouble.
Don’t be afraid. We've got a simple, step-by-step guide to fixing any hard drive failure, plus tips to prevent problems before they happen. Before you look for a screwdriver, try this first.
Folds softlyWhen your computer hard drive fails, the first thing to do is to check the computer's BIOS (Basic Input/Output System) settings. If your hard drive has the wrong number of capacities, the entire system may be disconnected. You may be able to solve the problem just by changing some settings.
Check BIOS settings
Press the key that brings up the computer BIOS settings options - usually F2 or DEL. Depending on the BIOS manufacturer, you may see a further list of options, or you may be taken directly to where you want it: the standard BIOS options screen.
In the standard BIOS options screen, look for the Hard Drive or IDE Device option. First look at the hard drive specifications table in your hand, then check items such as SIZE or MB in the BIOS, and then look at the numbers - the two should be very close. If the BIOS settings are inconsistent with the size of the hard drive actually installed in the computer, please increase the size. Lose some MB. These settings must correctly correspond to the actual specifications of the hard drive installed in the computer. Otherwise, the BIOS will think that the hard drive is broken.
If the number is incorrect. Or the word "Not Installed" is displayed where the number should appear, then you must make some changes. Fortunately, most new BIOS settings have the option to automatically identify the installed hard drive (Auto). After selecting this item, the BIOS will check the hard disk, read the setting data in the hard disk, and then automatically fill in the blanks with the data.
If this doesn’t work... If you try automatic recognition (or your BIOS automatically tries), but the BIOS cannot recognize the hard drive, then the problem is more serious. Now it's time to turn off the computer, unplug it, and remove the computer case. Roll up your sleeves and do a few basic hardware checks.
It is folded hardBefore opening your system, you should first touch the metal frame of the computer to release static electricity and prevent damage to system components. Then unplug the computer. (Note: If you stand up and move around after turning on the computer, you will have to plug it back in, reground it, and then unplug it to make sure there is no static electricity on you.)
Check the hard drive connector
Take the casing off the computer and use a flashlight to inspect the connectors connected to the hard drive. The drive itself has two connectors: a power connector for the four-wire cable that connects the drive to the power supply, and a data cable connector that connects the drive to the motherboard. If the connector comes loose, reattach it—be careful not to bend your foot. The connectors on both cables are usually designed to only plug in one way, so it should be impossible to plug them in the wrong way.
Also check the end of the long, thin cable that is not connected to the hard drive to make sure it is connected to the motherboard. If you find a loose connector, plug it back in. If its connector is not loose, plug it back in. If its interface is not specially designed for connectors, you should carefully check whether there is a small "I" printed on the board. That's where foot 1 should be facing.
Pushing
Prolonged electrical expansion and contraction will cause the pins in the connector to be in poor contact with each other, which is not detectable by just looking. So when you open the case, you can gently shake each connector connected to the hard drive and motherboard - better yet, pull each connector apart and then reconnect it to restore contact. Also, touch your cable data lines to test them. If it becomes stiff, try replacing it with a new one - it's possible that one of the cables encased in the insulation is broken. But make sure you are replacing the same type of cable. Once you've done these things, plug the power back in, start the computer, and see what happens.
The Ultimate Folding CountermeasureYou used the flashlight to shine up and down everything inside the computer. You fumbled with all the cables, replugged connectors, and even changed wires. The hard drive still didn't move.
Call Customer Support It’s time to surrender and call customer support. Try asking your computer seller or hard drive manufacturer's technicians first. Maybe they've faced the same problem before, or even have an easy solution beyond what we've talked about.
However, if you finally find out that the sad fact is that your hard drive has gone to hell, please check carefully - even if your computer has passed the shelf life, the hard drive may still be within the shelf life. Although most computer sellers offer a warranty period of one to three years when selling complete machines, hard drive manufacturers usually offer a warranty of two to five years. And their warranty usually not only covers the postage cost of the original hard drive purchased, but should also cover the replacement of the hard drive with a new one.
Keep your hard drive healthy
Finally, it’s about maintaining a healthy hard drive. Hard disk scanning tools such as ScanDisk are often used to check for bad blocks. This tool is included in the accessories of Windows 95/98. It can help you avoid possible problems or resolve them before they become serious.

Folding failure phenomenon
A few days ago, the author's system (WinXP) suddenly failed to start (the author's computer configuration: MSI KT333+8233A, WestJet Barracuda IV 60G), The phenomenon is that it always stays on the startup screen and cannot enter the operating system. At first, I didn't pay much attention to it. I thought there might be a problem with the startup file and I could just fix it. But it didn't work after several attempts.
Folding analysis and solutionThe author thought that it might be a virus, and the fault remained after anti-virus. After reinstalling the system, the startup speed is very slow and the hard disk light flashes wildly. After entering the system, I measured the transmission rate of the hard disk and found that it was only 4MB per second! I thought about the transmission mode problem and opened the device manager. Sure enough, the hard disk was working in PIO mode. The strange thing is that after I manually adjusted the hard disk working mode , after restarting the system, I found that the hard disk working mode is still PIO mode!
The basic problem has been found here, the hard disk has lost support for the DMA working mode. The author went to WestJet's official website to download a special tool to change the working mode of the hard disk, but it was detected that the default mode of the hard disk at this time was DMA, and I used the special error checking tool of WestJet hard disk to conduct a comprehensive check. Everything turned out to be normal! The author began to feel that the failure might be caused by hardware. After careful inspection of the hard drive, the problem was finally discovered. A pin was broken in the IDE interface of the hard drive. The author quickly unscrewed the screws with a Torx screwdriver, removed the metal protective plate and sponge from the outside of the WestJet hard drive, exposed the circuit board, found a jumper pin from elsewhere, filled it to the original missing pin, and soldered it. Then restore the hard drive and reinstall the system to resolve the problem.

Collapse startup failure
During the use of the computer, we may all encounter the problem that the computer cannot start. There are many reasons for system startup failure, many of which are related to the hard disk. Under normal circumstances, when the hard disk fails, the BIOS will give some English prompt information. Due to motherboards from different manufacturers or different versions of BIOS, there may be some differences in the prompt information, but they are basically the same. Let's take the more common Award BIOS as an example to discuss how to use the prompt information it gives to determine and deal with the failure of the hard disk to start.
1.Hard disk controller failure. This is one of the most common error messages. When this happens, you should carefully check whether the connection plug of the data cable is loose, whether the connection is correct, or whether the hard disk parameter settings are correct.
2.Date error. When this happens, there are irreparable errors in the data the system reads from the hard disk or there are bad sectors on the disk. At this time, you can try to start the ScanDisk program to scan and correct logical errors in the sectors. If the bad sectors are physical bad sectors, you need to use special tools to try to repair them.
3.no boot sector on hard disk drive. In this case, the boot sector on the hard disk may be damaged, usually because the boot sector of the hard disk system has been infected with a virus. When encountering this situation, you must first use the latest version of anti-virus software to thoroughly check for viruses in the system, and then use software with boot sector recovery functions such as KV3000 to try to restore the boot record. If you are using WinXP system, you can start the "Recovery Console" and call the FIXMBR command to restore the master boot sector.
4.Reset Failed (hard disk reset failure), Fatal Error Bad Hard Disk (hard disk fatal error), DD Not Detected (hard disk is not detected) and HDD Control Error (hard disk control error). When any of the above prompts appear, it is usually a fault on the hard disk control circuit board, the hard disk interface circuit on the motherboard, or the mechanical part inside the disk body. In this case, you can only ask a professional to repair the corresponding control circuit or replace it directly. harddisk.
Folding Bad Sectors FaultThrough the above learning, King has some understanding of how to solve the problem of hard disk failure. The next thing King wants to know is of course how to deal with his own hard disk that already has bad sectors. In this issue, the teacher will introduce to King the faults of logical bad sectors and physical bad sectors and the corresponding repairs. But before the lecture began, the teacher reminded King that he must be cautious and careful in doing this work.
Logical bad sectors
出現邏輯壞道是在電腦的日常使用中容易出現的一種硬碟故障，邏輯壞道其實就是磁碟磁軌上面的校驗資訊(ECC)與磁軌的資料和伺服資訊不符。造成這種故障的主要原因通常都是因為一些程式的錯誤操作，或是該處扇區的磁性介質開始出現不穩定現象的先兆。邏輯壞道在一般電腦使用上的表現，就是檔案存取時出錯或做硬碟複製時，當到達出錯部位後，因彈出出錯資訊視窗而無法繼續下去。 消除這種邏輯壞道的方法比較簡單，很多專用軟體如:DM、NORTON的DISK DOCTOR等都能做到，但最常用的還是Windows自帶的"磁碟掃描"功能。對於FATl6或FAT32分割區來說，可以在DOS實模式下用Scandisk掃描磁碟，此時系統可將邏輯出錯的磁區標註出來，以後在進行存取操作時就會避開這些磁區。由於這些軟體的使用方法較為簡單且也多有介紹，這裡也就不過多地講解了。
但是，假如採用的是NTFS分割區且安裝Windows XP系統，由於它沒有Scandisk這個工具，故只能使用Chkdsk這個工具了。 Chkdsk工具會基於所使用的檔案系統，建立和顯示磁碟的狀態報告。另外Chkdsk也能夠列出並修正磁碟上的錯誤。不過如果不帶任何參數的話，chkdsk將只顯示目前磁碟機中磁碟的狀態，而不會修正任何的錯誤，要修正錯誤則必須包含/f參數。
物理壞道
硬碟物理壞道是比較常見的硬碟故障。實際上它是因為讀寫突然斷電、震盪、刮傷等"硬"原因，導致-些扇區的磁介質失去了磁記憶能力而造成的。通常情況下，這樣的損壞修復起來都比較麻煩。因為，在硬碟內部的磁軌清單中，這個磁區是被標示為正常的，而壞道也是物理性存在的。所以，它無法透過掃描、格式化、低格或啟動磁區的方法來消除，必須將這個磁區加入設定在硬碟內部的系統保留區，告訴磁碟這些磁軌已經不能使用了，才能在硬碟控制系統的可見範圍內消除這個壞道。當然，這樣做需要使用一些專用軟體，對一般用戶來講維修有些困難。
不過有些硬碟廠商會提供原廠的工具軟體，如IBM/日立的DFT和西部資料的Data LifeGuard Diagnostics。這些原廠的工具軟體不但掃描速度快，而且辨別準確率也很高，能夠對付較為普遍的硬碟物理壞道故障。因此對硬碟內部進行操作還是原廠的軟體較為可靠，除非原廠工具無法解決問題，否則不建議使用第三方的工具軟體。
相對於上面這種比較高級的隱藏方式，對於那些要求不高的用戶來說，則可以通過"壞盤分區器"FBDISK和Disk Genius這一對軟體的組合，完成將壞道所在位置做成分區隱藏起來的任務。其具體的操作簡要介紹如下:
首先，將下載來的軟體複製到一台正常使用的電腦的C盤根目錄下，再把出現物理壞道的硬碟作為第2硬碟掛接在該電腦上。接著啟動到DOS的實模式下，並執行Disk Genius的可執行程式Diskgen，然後按"Ctrl+Alt"組合鍵，選擇"硬碟"選單下的"第2硬碟"。這時就可以看到第2硬碟的具體分區情況了。要重新規劃這塊硬碟，就可以把所有分割區都刪除掉，隨後記憶體就退出。
接著執行FB Disk，選擇要偵測的硬碟後按"Y"開始掃描。如果硬碟存在壞道，則FB Disk會自動顯示出它在哪個磁區和磁軌。掃描完成後它可以把所有的壞道都羅列出來，並詢問是否要寫入硬碟。若按"Y"將會自動將壞道隱藏起來，最後按下Esc鍵退出。
隨後再次運行Diskgen，這時就可以看出經過FB Disk處理後的磁碟情況，此時壞道處會呈現-種灰白色。透過Diskgen再稍微將隱藏物理壞道的分區擴大一些。最後，將這些壞道全部隱藏在一個分區裡，修復工作即告結束。
兩款軟體搭配使用是因為，經過FBDisk處理後的硬碟可能會有很多分區，而受軟體本身最多4個主分區的限制，會導致硬碟利用率不高的後果。而透過Diskgen的配合，就可以很好地解決這個問題。
折疊編輯本段壞道維修
Scandisk磁碟掃描程式是解決硬碟邏輯壞道最常用的工具，而我們常見的Format指令不能對任何硬碟壞道起到修補作用，這點大家需明白。如果硬碟出現了壞道，我們可在Windows系統環境下，在"我的電腦"中選取要處理的硬碟符，選擇其"屬性"，在出現的"工具"按鈕中選擇"查錯狀態" ，點擊"開始檢查"，再在"掃描類型"中選"全面檢查"，並將"自動修復錯誤"打上"勾"，然後"開始"即可，它將對硬碟盤面做完全掃描處理，並且對可能出現的壞簇做自動修正。其次，在DOS狀態下，硬碟有壞道，電腦在啟動時一般會自動執行Scandisk進行掃描，並將壞簇以黑底紅字的"B"(bad)標示。當然，如果系統在啟動時不進行磁碟掃描或已無法進入Windows系統，我們也可用軟碟或光碟啟動碟啟動電腦後，在對應的磁碟區下，如"A:"下執行Scandisk *:(註: *為要掃描的硬碟)，回車後來對相應需要掃描修復的硬碟分區進行修理。
如果硬碟上出現了無法修復的壞簇或物理壞道，大家可用一些磁碟軟體將這些壞道單獨分為一個區並隱藏起來，這樣可令你的硬碟延長使用壽命。
如係統顯示"TRACK 0 BAD，DISK UNUSABLE"，意思為"零磁軌損壞，硬碟無法使用"或用磁碟掃描程式掃描其它硬碟時其0磁區出現紅色"B"。硬碟0區損壞，是大家比較頭痛的故障，一般人往往會這樣故障的硬碟報廢處理。其實合理運用一些磁碟軟體，把報廢的0區屏蔽掉，而用1區取而代之就能起到起死回生的效果，這樣的軟體如Pctools9.0和NU8等。
方法一:我們就先以Pctools9.0為例來作說明。一塊2.1G硬碟出現上述故障，用碟啟動電腦後，執行 Pctools9.0目錄下的DE.EXE檔。接著選主選單Select中的Drive，進去後在Drive type項選Physical，按空白選定，再按Tab鍵切換到Drives項，選取hard disk，然後OK回車後回到主選單。開啟Select選單，這時會出現Partition Table，選取進入後出現硬碟分割表資訊。該硬碟有兩個分區，找到C區，該分區是從硬碟的0柱面開始的，那麼，將1分區的Beginning Cylinder的0改成1就可以了，保存後退出。重新啟動電腦後按Del鍵進入COMS設置，運行"IDE AUTO DETECT"，可以看到CYLS由782變成781。儲存退出後重新分割區格式化該硬碟，使其起死回生。
方法二:諾頓NU8.0也較好用。例如一塊1.28G硬碟出現0磁軌損壞故障，進入NU8工具包目錄，執行其主程式 NORTON.EXE，然後可先選"補救碟"RESCUE選項對該硬碟的引導區、分割表等資訊進行備份。接著選擇"磁碟編輯器DISKEDIT"，成功運行後選"物件OBJECT"，選"分區表"後可見本硬碟的參數如下:面SIDE為0-63，簇CYLINDER為0-255，扇區SECTOR為1 -63，其主引導記錄和分區表資訊就應該在0面0柱1扇區。我們要做的事就是把其C盤的起始扇區從0面0柱1扇區改為0面1柱1扇區，移動遊標手工修改即可。另外需要說的就是，改動數值要根據具體情況而定。最後隨身碟後退出重啟電腦，用Format指令格式化硬碟即可正常使用了。要特別留意的是，修好後的硬碟一定不要再用DOS下的Fdisk等分割工具對其進行重新分割操作，以免其又改變硬碟的起始柱面。
如果以上各招都不見效，那麼就得使用主機板自帶的硬碟低格程式或硬碟廠商隨盤贈送的低格程式如DM、LFormat等對硬碟全碟進行低階格式化處理了，它可對硬碟的一些壞道進行重新整理排除。
